Re: new link failing on duplicate names in different namespaces

We can not give the guarantee that a new network device will only live
in and have a unique name in a single network namespace until we get
rid of dev_change_net_namespace in the code.

In fact in case of IFLA_LINK_NETNSID, with Cong's patch, we will first check
that the name is unique in link_net and after dev_change_net_namespace() will
check that the name is also unique in the final net, else the command will fail
(and the device is not created).
